Ok, ill put it like this...Sentry moving at a speed faster than gabriel can think tears off his head and throws it into the sun (little bit exaggerated, but that could easily happen)
he just adapts to sentrys powers he can't be hurt if someone wants to brake his bones they will becme flexible if someone tryes to burn him he will become fire proof if someone tryes to drown him he will grow limbs if you put him in darkness he will see in darkness if you try to kill him with gas he will adapt and like prof x said the possibilities are endless and he can shut off sentry's brain like he did to rachel summers
No they arent, Sentry can move faster than it takes for people to think, therefore Vulcan cannot adapt to a thing, seeing as he hasnt even seen the sentry or thought about adapting. Thus Sentry speeds past ripping off Vulcan's head and flying off to his threat face it...vulcan loses
If Sentry like Superman and the Flash, thinks at a superhuman rate, meaning he thinks faster then Vulcan then yes Sentry will take it.
However if Sentry thinks at a human rate like Gabriel, then Gabriel will take it. As Sentry still has to think to do a Speed Blitz.
Uh, you forget, he needs to think to be able to do that...and if sentry can get there before vulcan can think (which he can!) than i think Sentry can defeat Vulcan with ease. and your little black hole thing wont work either seeing as he can just make his way back which he did when genis put him into one
